In recent years, unprecedented growth of mobile data traffic is witnessed due to the rapid proliferation of various wireless communication technologies, applications, and services.
In general, 5G standardization goals are defined based on enhanced mobile broadband, ultra-reliable and low latency communications and massive machine-type communications to address the key wireless communication requirements.
To fulfill the above requirements, different techniques such as Millimeter-wave (mmWave) communication, massive multiple-input multiple-output (MIMO), new waveform design, ultra-dense network (UDN), etc. are proposed [1]}.
Further, spectral and energy efficient wireless systems design is a key requirement for 5G and beyond wireless networks, and recently proposed intelligent reconfigurable surface (IRS)-assisted wireless system design can improve spectral and energy efficiency significantly by enhancing the received signal power at a user node [2]}.
